摘要

为研究水泥沥青乳液(以下简称CAE)基层材料的循环剪切变形和液化强度，进行了一系列不排水循环三轴试验。试验所用材料为颗粒状基层材料和水泥、沥青乳液。结果表明，松散颗粒状基层材料的液化阻力R L20为0.12，沥青稳定基层材料的液化阻力R L20为0.22，水泥稳定基层材料的液化阻力R L20为0.47,CAE基层材料的液化阻力R L20为0.56。结果表明，CAE基层材料的液化强度是颗粒状基层材料的4.7倍左右。

FUNDAMENTAL STUDY ON CYCLIC SHEAR BEHAVIOR IN UNDRAINED CONDITION OF CEMENT ASPHALT EMULSION STABILIZED SOIL

To investigate the cyclic shear deformation and the liquefaction strength of the cement asphalt emulsion (hereafter called “CAE”) base course material, a series of undrained cyclic triaxial tests were performed. The materials used for the test are granular base course material and cement, asphalt emulsion. As a results, the liquefaction resistance R L20 of loose granular base course material was 0.12 and that of asphalt-stabilized base course material was 0.22, that of cement-stabilized base course material was 0.47, that of CAE base course material was 0.56. From the result, CAE base course material had about 4.7 times more liquefaction strength than that of granular base course material.
